Test Procedures

Sample Preparation:

Select a representative sample of plastic, film, or coated material.

Inspect the surface to ensure it is free of contamination or defects that may affect the test.

Setup:

Install the sample securely in the sample holder.

Select the appropriate scratch tip and load according to the test standard.

Program scratch distance, speed, and load using the touch screen interface.

Testing Procedure:

Perform scratch tests along the left-to-right direction.

Record force and scratch characteristics using the built-in force sensor.

Repeat as necessary to achieve statistically relevant results.

Use stored profiles for repeated or comparative testing.

Maintenance Information

Regularly clean scratch tips and sample holders to prevent contamination.

Verify force sensor calibration periodically to maintain accuracy.

Check vertical load and horizontal movement mechanisms for smooth operation.

Inspect electrical and control systems to ensure proper function.
